Ricardo Vieira Carlos, Marcelo Luis Abramides Torres, Hans Donald de Boer
Heart transplantation is a frequent procedure in the treatment of end-stage cardiac dysfunction. Therefore, these patient populations will also be more frequent exposed to other more common surgical procedures after their transplantation. Anesthesiologist should be aware in their assessment of these patients, especially regarding some specific issues related to patients with a history of heart transplantation, like reversal of neuromuscular block. Several reports described that cholinesterase inhibitors drugs, like neostigmine, may produce a dose-dependent life-threatening bradycardia in heart transplant recipients while other publication described the safe use of neostigmine...

BACKGROUND AND OBJECTIVES: The weight parameters for use of sugammadex in morbidly obese patients still need to be defined. METHODS: A prospective clinical trial was conducted with sixty participants with body mass index≥40kg·m-2 during bariatric surgery, randomized into three groups: ideal weight (IW), 20% corrected body weight (CW20) and 40% corrected body weight (CW40). All patients received total intravenous anesthesia. Rocuronium was administered at dose of 0...

Leonardo Riedi de Andrade, Yara Marcondes Machado Castiglia
BACKGROUND AND OBJECTIVE: Some surgical procedures such as laryngoplasty require patients to remain conscious during the intraoperative phase in order to enable speech monitoring. Dexmedetomidine and remifentanil were used in this study, since they promote appropriate patient collaboration with facilitated awakening, and are rapidly eliminated. CASE REPORT: The patient complained of dysphonia, which had resulted from unilateral vocal fold paralysis after previous thyroidectomy...

BACKGROUND AND OBJECTIVES: Postoperative cognitive dysfunction is common after cardiac surgery. Adequate cerebral perfusion is essential and near infrared spectroscopy (NIRS) can measure cerebral oxygenation. Aim of this study is to compare incidence of early and late postoperative cognitive dysfunction in elderly patients treated with conventional or near infrared spectroscopy monitoring. METHODS: Patients undergoing coronary surgery above 60 years, were included and randomized to 2 groups; control and NIRS groups...

Suman Arora, Priyanka Gupta, Virender Kumar Arya, Nidhi Bhatia
BACKGROUND: Efficacy of preoxygenation depends upon inspired oxygen concentration, its flow rate, breathing system configuration and patient characteristics. We hypothesized that in actual clinical scenario, where breathing circuit is not primed with 100% oxygen, patients may need more time to achieve EtO2≥90%, and this duration may be different among various breathing systems. We thus studied the efficacy of preoxygenation using unprimed Mapleson A, Bain's and Circle system with tidal volume breathing at oxygen flow rates of 5L...

BACKGROUND: Post-operative delirium is a serious complication in patients undergoing major abdominal surgery. It remains unclear whether peri-operative hemodynamic and perfusion variables affect the risk for postoperative delirium. The objective of this pilot study was to evaluate the association between perfusion and hemodynamics peri-operative with the appearance of post-operative delirium. METHODS: Prospective cohort study of adults 60 years or older undergoing elective open colon surgery...

BACKGROUND AND GOAL OF STUDY: After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. MATERIALS AND METHODS: We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n=38) or standard postoperative analgesia (n=38)...

Ali Sait Kavakli, Nilgun Kavrut Ozturk
Atrial myxoma is a benign tumor of the heart that occurs primarily in the left atrium. Floating or large left atrial myxomas frequently cause functional mitral stenosis, may also affect mitral valve structure and flow, and lead to mitral regurgitation. Systemic embolization occurs in around 30% of cases either from tumor fragmentation or complete tumor detachment hence it should be removed as soon as it is detected. Intraoperative transesophageal echocardiography has a vital importance in the surgery. After resection of myxoma, intraoperative transesophageal echocardiography must be performed to rule out residual mass...

Marcia Hiray Pera, Maria Angela Tardelli, Neil Ferreira Novo, Yara Juliano, Helga Cristina Almeida da Silva
INTRODUCTION: ENT patients with obstructive sleep apnea syndrome have, in addition to anatomical obstacles, a tendency of collapsing the upper airways. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the Stop Bang questionnaire has been highlighted because it is summarized and easy to apply. OBJECTIVES: Evaluate through the Stop Bang questionnaire whether patients undergoing ENT surgery with a diagnosis of obstructive sleep apnea syndrome have a higher risk of complications, particularly, the occurrence of difficult airway...

BACKGROUND AND OBJECTIVES: Major burn surgery causes large hemorrhage and coagulation dysfunction. Treatment algorithms guided by ROTEM® and FVIIa reduce the need for blood products, but there is no evidence regarding factor XIII. Factor XIII deficiency changes clot stability and decreases wound healing. This study evaluates the efficacy and safety of factor XIII correction and its repercussion on transfusion requirements in burn surgery. METHODS: Randomized retrospective study with 40 patients undergoing surgery at the Burn Unit, divided into Group A, those with factor XIII assessment (n = 20), and Group B, those without assessment (n = 20)...

INTRODUCTION: Anesthesia emergence delirium (AED) is a self-limiting clinical phenomenon very common in children. Although pathophysiology is still uncertain, some factors seem to be involved, such as rapid awakening in an unknown environment, agitation during anesthetic induction, preoperative anxiety, environmental disorders, use of preanesthetic medication, use of inhalational anesthetics, and postoperative pain. OBJECTIVE: To determine the prevalence and risk factors associated with AED in children undergoing outpatient surgery...

INTRODUCTION: Since anesthesia complications associated with unexpected difficult airway are potentially catastrophic, they should be avoided. The modified Mallampati test and jaw-thrust maneuver enable the identification of difficult airway. The aim of this study was to associate the modified Mallampati test and the jaw-thrust maneuver with laryngoscopy (Cormack-Lehane) in an attempt to identify a better predictor of difficult airway in an adult population undergoing elective surgery...

BACKGROUND AND OBJECTIVE: There are few data defining the period of time in which preoperative tests can be considered valid. The purpose of this study was to determine the likelihood of changes in the results of preoperative tests previously normal in relation to time, and the impact of these changes on postoperative outcomes. METHODS: A total of 970 patients with normal preoperative tests before the first surgery and who required a new intervention were included...

Ana Filipa Vieira da Silva Ferreira Marques, Teresa Alexandra Santos Carvalho Lapa
BACKGROUND AND OBJECTIVES: It has been speculated that the use of anesthetic agents may be a risk factor for the development of Alzheimer disease. The objective of this review is to describe and discuss pre-clinical and clinical data related to anesthesia and this disease. CONTENT: Alzheimer disease affects about 5% of the population over 65 years old, with age being the main risk factor and being associated with a high morbidity. Current evidence questions a possible association between anesthesia, surgery, and long-term cognitive effects, including Alzheimer disease...

BACKGROUND AND OBJECTIVES: Pain is an aggravating factor of postoperative morbidity and mortality. The aim of this study was to compare the effects of methadone versus morphine using the numerical rating scale of pain and postoperative on-demand analgesia in patients undergoing myocardial revascularization. METHOD: A randomized, double-blind, parallel clinical trial was performed with patients undergoing coronary artery bypass grafting. The subjects were randomly divided into two groups: Morphine Group (MoG) and Methadone Group (MeG)...
